ELECTRONIC DEVICE INCLUDING OPTICAL SENSOR MODULE

Description

BACKGROUND

Field

[0001] The disclosure relates to an electronic device including an optical sensor module.

Description of Related Art

[0002] One of current trends in developing electronic devices to meet customer's demands is slimming a device body, for example, reducing a thickness of the electronic device. In addition, such electronic devices are being developed to increase their stiffness, strengthen their design aspects, and differentiate their functional features.

[0003] To realize a slim electronic device, a plurality of electronic components of the electronic device should be efficiently disposed in an inner space of the electronic device. In addition to this condition, the plurality of electronic components should be properly disposed to reliably perform their functions. In particular, such an efficient arrangement structure inside the electronic device may be further required in case of electronic components related to a large-screen display.

[0004] Currently, mobile electronic devices are being improved to relatively increase the area of a display without changing the overall size. Therefore, as the display is being improved to substantially occupy most of the front surface of the electronic device, an optical sensor module such as a proximity sensor module or an illumination sensor module is also being improved to have a corresponding arrangement structure. For example, the optical sensor module may be disposed in the inner space of the electronic device, underlying the display, to detect external environments through a portion of a display area. The optical sensor module may include a light emitting structure and a light receiving structure both of which are disposed in a module housing and spaced apart from each other. For example, the optical sensor module may perform a sensing operation in a manner that the light emitting structure emits light through the display area and then the light receiving structure receives light reflected by external objects.

[0005] However, when the optical sensor module is disposed under the display area (e.g., an active area) of the display, a spot phenomenon by the photoelectric effect may occur in the display area because the light emitted from the light emitting structure leaks to a display device (e.g., an OLED device). In addition, when the light emitting structure is disposed under the display area in which transmittance gradually decreases according to depth, sensing performance may be degraded due to crosstalk caused by diffused reflection. Further, in case of partial-off control that turns off a certain portion of the display area for the operation of the optical sensor module, a relatively large portion corresponding to the optical sensor module should be turned off. This is contrary to the efficient operation of the display area.

[0006] EP3490233 A1 appears to disclose a display screen component and an electronic device for improving an accuracy of controlling a state of a display screen. US 2018/364869 appears to disclose an electronic device comprising a display panel; a light emitting module disposed adjacent to the display panel, and configured to output light; and a light receiving module disposed in a portion of the display panel or below or beneath the display panel and configured to detect light of the outputted light that is reflected by the by an external object. US 9874907 appears to disclose a display device including a cover window having a display region and a non-display region surrounding the display region on a same plane, an optical sensor member including a light emitting portion and a light receiving portion, the optical sensor member being adjacent to a first surface of the cover window and overlapping the non-display region. CN108600421 appears to disclose an electronic device comprising a display screen, an infrared sensor and a light-blocking element, wherein the display screen comprising a display area and a non-display area.

[0019] The input device 150 may receive a command or data to be used by other component (e.g., the processor 120) of the electronic device 101, from the outside (e.g., a user) of the electronic device 101. The input device 150 may include, for example, a microphone, a mouse, a keyboard, or a digital pen (e.g., a stylus pen).

[0020] The audio output device 155 may output sound signals to the outside of the electronic device 101. The audio output device 155 may include, for example, a speaker or a receiver.

The display device 160 may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. The display device 160 may include touch circuitry adapted to detect a touch, or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of force incurred by the touch.

[0022] The audio module 170 may convert a sound into an electrical signal and vice versa. The audio module 170 may obtain the sound via the input device 150, or output the sound via the audio output device 155 or a headphone of an external electronic device (e.g., an electronic device 102) directly (e.g., wiredly) or wirelessly coupled with the electronic device 101.

[0023] The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the AP) and supports a direct (e.g., wired) communication or a wireless communication. The communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth^™, wireless-fidelity (Wi-Fi) direct, or a standard of the Infrared Data Association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the SIM 196.

[0031] The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. The antenna module 197 may include an antenna including a radiating element including a conductive material or a conductive pattern formed in or on a substrate (e.g., a PCB). The antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. Another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

[0032] At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

[0033] Commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. All or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

For example, the camera module 205, the sensor module 204, or the indicator may be arranged in the internal space of an electronic device 200 so as to be brought into contact with an external environment through an opening of the display 201, which is perforated up to a front plate 202. Some sensor modules 204 may be arranged to perform their functions without being visually exposed through the front plate 202 in the internal space of the electronic device. For example, in this case, an area of the display 201 facing the sensor module may not require a perforated opening.

[0066] The electronic device (e.g., the electronic device 300 in FIG. 3) according to the present invention includes an optical sensor module 500 disposed by being attached to a rear surface of the display 400. According to an embodiment, the optical sensor module 500 may include various kinds of sensor modules that detect external environments by detecting light emitted through the display 400 and then reflected on external objects.

[0067] According to the present invention, the optical sensor module 500 is capable of emitting and receiving light. However, the additional layer 440 does not allow the penetration of light. Therefore, in order to allow the transmission of light emitted from or reflected toward the optical sensor module 500, the additional layer 400 may have one or more through-holes 4412, 4422, 4442, and 4452 formed at a position corresponding to the underlying optical sensor module 500. In another configuration not according to the present invention, when the optical sensor module 500 is the camera sensor module or the TOF module, the display panel 430 and the POL 432 may also have through-holes (not shown) formed at corresponding positions.

[0068] FIG. 5A is a diagram illustrating a front surface of an example display 400 according to various embodiments of the disclosure. FIG. 5B is a diagram illustrating a rear surface of the example display 400 according to various embodiments of the disclosure.

[0069] Referring to FIGS. 5A and 5B, the display 400 may be attached to the rear surface of the front cover 320 through the adhesive member as described above. According to an embodiment, the display 400 may include the display panel 430 and the additional layer 440 attached to the rear surface 430b of the display panel 430. According to an embodiment, the display panel 430 may have the front surface 430a (e.g., the first surface) facing the front cover 320, and the rear surface 430b (e.g., the second surface) opposite to the front surface 430a and allowing the additional layer 440 to be attached.

[0070] According to various embodiments, as shown in FIG. 5B, the display 400 may include a flat portion 411, a bendable portion 412 folded from the flat portion 411 to the rear surface of the display 400, and a flexible printed circuit board (FPCB) 413 electrically connected to the bendable portion 412. According to an embodiment, the display 400 may include a control circuit 4121 mounted on the bendable portion 412. According to an embodiment, the control circuit 4121 may include, for example, a display driver IC (DDI) or a touch display driver IC (TDDI) mounted on the bendable portion 412. According to an embodiment, the DDI or TDDI may be mounted on the bendable portion 412 in, for example, a chip-on-panel (COP) structure. According to an embodiment, at least a part of the FPCB 413 and the bendable portion 412 may be folded to the rear surface of the display 400 and attached to the additional layer 440 through bonding or taping. According to an embodiment, the display 400 may include a plurality of elements 4131 disposed on the FPCB 413, and an electronic connector 4132 electrically connected to a printed circuit board (e.g., the PCB 340 in FIG. 3) of an electronic device (e.g., the electronic device 300 in FIG. 3). According to an embodiment, the plurality of elements 4131 may include, for example, and without limitation, a touch IC, a flash memory for display, an ESD protection diode, a decoupling capacitor, or the like.

[0071] According to the present invention, as shown in FIG. 5A, the display panel 430 includes a display area 431 (e.g., an active area), which substantially occupies most area, and a non-display area 432 (e.g., an inactive area or a black matrix (BM) area) disposed to surround at least in part the periphery of the display area 431 and having a certain width. The non-display area 432 includes a first non-display area 4321 disposed to surround at least in part the periphery of the display area 431, and a second non-display area 4322 disposed to surround at least in part the periphery of the first non-display area 4321. According to the present invention, the first non-display area 4321 has a greater transmittance than the display area 431.

[0072] According to the present invention, the display 400 includes the optical sensor module 500 that is disposed at a suitable place on the rear surface of the additional layer 440 (e.g., the conductive member). The optical sensor module 500 includes a flexible printed circuit board (FPCB) (e.g., the FPCB 520 in FIG. 7), a module housing 510 mounted on the FPCB 520, a light emitting structure (e.g., including light emitting circuitry) 501 disposed in the module housing 510, and a light receiving structure (e.g., including light receiving circuitry) 502 disposed in the module housing 510 to be spaced apart from the light emitting structure 501. When the display 400 is viewed from above, the optical sensor module 500 may be disposed such that the light emitting structure 501 overlaps the first non-display area 4321 and the light receiving structure 502 overlaps the display area 431. When the light emitting structure 501 is disposed within the first non-display area 4321 having a relatively high transmittance to avoid the display area 431, the degradation of sensing performance due to diffused reflection can be prevented and/or reduced. In addition, a spot phenomenon that may occur in the display area 431 by light emitted from the light emitting structure 501 and leaking to the display device may be prevented and/or reduced.

[0073] FIG. 6 is a combination of a cross-sectional view and a plan view illustrating an arrangement relationship between a display panel 430 and an optical sensor module 500 according to various embodiments of the disclosure. The cross-section view of FIG. 6 is taken along the line A-A' of FIG. 5A.

[0074] Referring to FIG. 6, the display panel 430 disposed on the rear surface of the front cover 320 includes the display area 431 having a first transmittance and the non-display area 432 disposed adjacent to the display area 431. The non-display area 432 includes the first non-display area 4321 adjacent to the display area 431 and having a second transmittance greater than the first transmittance, and the second non-display area 4322 adjacent to the first non-display area 4321 and having a transmittance of 0%. According to an embodiment, the second non-display area 4322 may have a printed layer P formed on the outer surface thereof. According to an embodiment, the first transmittance may range, for example, from about 1% to about 4%. According to an embodiment, the second transmittance may range, for example, from about 5% to about 10%.

[0075] According to the present invention, the display area 431 of the display panel 430 contains a plurality of pixels, and the non-display area 432 contains driving circuits 4331 (e.g., gate driving circuits) disposed to control the plurality of pixels, and wiring structures 4332 electrically connecting the driving circuits 4331. According to the present invention, the second transmittance of the first non-display area 4321 is determined by adjusting the arrangement density of the driving circuits 4331 and the wiring structures 4332. For example, the second transmittance of the first non-display area 4321 may be determined depending on the arrangement density of the driving circuits 4331 and the wiring structures 4332 arranged in the first non-display area 4321 to be lower than the arrangement density of the driving circuits 4331 and wiring structures 4332 arranged in the second non-display region 4322.

[0076] According to to the present invention, when the display panel 430 is viewed from above, the optical sensor module 500 may be disposed such that the light emitting structure 501 overlaps the first non-display area 4321 and the light receiving structure 502 overlaps the display area 431. With this arrangement, the light emitting structure 501 can emit light through the first non-display area 4321 having the relatively high second transmittance, and the light receiving structure 502 disposed under the display area 431 can smoothly receive light reflected from the outside.

[0077] FIG. 7 is a combination of a cross-sectional view and a plan view partially illustrating an example electronic device 700 including an optical sensor module 500 according to the present invention.

[0078] The electronic device 700 shown in FIG. 7 may be similar, at least in part, to the electronic device 101 of FIG. 1, the electronic device 200 of FIGS. 2A and 2B, or the electronic device 300 of FIG. 3, or may include other embodiments of the electronic device.

[0079] Referring to FIG. 7, the electronic device 700 may include a housing structure (e.g., the housing 210 in FIG. 2A) including a front cover 320 (e.g., a cover member, a front plate, a front window, or a first plate), a rear cover 380 (e.g., a rear cover member, a rear plate, a back window, or a second plate) facing in a direction opposite to the front cover 320, and a lateral member 310 surrounding an inner space 7001 between the front cover 320 and the rear cover 380. According to an embodiment, the lateral member 310 may include a support member 311 that extends at least partially into the inner space 7001 of the electronic device 700. According to an embodiment, the support member 311 may be formed by structural coupling with the lateral member 310. According to an embodiment, the support member 311 may have a structural shape for supporting at least a part of the optical sensor module 500 disposed under the additional layer 440 of the display 400.

[0080] According to the present invention, the electronic device 700 includes the display 400 disposed in the inner space 7001 to be visible from the outside through at least a portion of the front cover 320. According to an embodiment, the display 400 includes the display panel 430 attached to the front cover 320, and the additional layer 440 attached to the rear surface of the display panel 430. According to the present invention, the display panel 430 includes the display area 431 having the first transmittance, the first non-display area 4321 adjacent to the display area 431 and having the second transmittance greater than the first transmittance, and the second non-display area 4322 adjacent to the first non-display area 4321.

[0081] The electronic device 700 includes the optical sensor module 500 disposed in the inner space 7001 and attached to the additional layer 440 of the display 400. When the display panel 430 is viewed from above, the optical sensor module 500 is disposed such that the light emitting structure 501 overlaps the first non-display area 4321 and the light receiving structure 502 overlaps the display area 431. According to an embodiment, because the additional layer 440 does not allow the transmission of light, the additional layer 440 may have at least one through-hole 4401 formed up to the display panel 430 at a position facing the light emitting structure 501 and the light receiving structure 502. According to an embodiment, the at least one through-hole 4401 may be formed at each of a position corresponding to the light emitting structure 501 and a position corresponding to the light receiving structure 502. In another embodiment, the at least one through-hole 4401 may be formed as a single hole to correspond to both the light emitting structure 501 and the light receiving structure 502.

[0082] According to the present invention, the optical sensor module 500 includes the FPCB 520 and the module housing 510 mounted on the FPCB 520, and also include the light emitting structure 501 and the light receiving structure 502 both of which are disposed in the module housing 510, spaced apart from each other, and electrically connected to the FPCB 520. According to an embodiment, the optical sensor module 500 may further include an extension 521 extending from the FPCB 520, and an electrical connector 522 mounted at the end of the extension 521. According to an embodiment, the electrical connector 522 may be electrically connected to the PCB 340 (e.g., a main PCB) that is separately disposed in the inner space 7001 of the electronic device 700.

[0083] According to various embodiments, the optical sensor module 500 may be disposed in a manner that the FPCB 520 is attached to the additional layer 440 of the display 400 through at least one waterproof member 710 (e.g., a waterproof tape). According to an embodiment, the optical sensor module 500 may have a first sealing structure (S1) for sealing the module housing 510 through the at least one waterproof member 710 disposed between the additional layer 440 and the FPCB 520. For example, the at least one waterproof member 710 is disposed on the FPCB 520 to surround the module housing 510 and then attached to the additional layer 440, so that the optical sensor module 500 can be disposed under the display 400. According to an embodiment, the optical sensor module 500 may also have a second sealing structure (S2) for sealing even the FPCB 520 through at least one waterproof member 710 disposed between the additional layer 440 and the support member 311. According to an embodiment, because the optical sensor module 500 is attached to the rear surface of the additional layer 440 of the display 400 through the first sealing structure S1 and the second sealing structure S2, it is possible to prevent and/or reduce foreign matter and/or moisture from entering the through-hole 4401 formed in the additional layer 440. According to an embodiment, when the display 400 is disposed through the lateral member 310 and the support member 311 of the electronic device 700, the FPCB 520 may be attached to the support member 311 through the waterproof member 710 (e.g., a double-sided tape).

[0084] As such, the optical sensor module 500 according to embodiments of the disclosure is directly arranged under the display 400 using the FPCB 520 provided separately from the PCB 340. This arrangement can prevent and/or reduce sensing errors due to tilt tolerances (e.g., a tilt of the optical sensor module) and also allow an efficient layout design in which the optical sensor module 500 is disposed up to the uppermost portion (in a plan view) of the display 400 separately from the PCB 340.

[0085] FIG. 8 is a cross-sectional view partially illustrating an example electronic device 800 including a distance detection sensor module 810 not according to the present invention.

[0086] The electronic device 800 shown in FIG. 8 may be similar, at least in part, to the electronic device 101 of FIG. 1, the electronic device 200 of FIGS. 2A and 2B, the electronic device 300 of FIG. 3, or the electronic device 700 of FIG. 7.

[0087] In describing FIG. 8, the substantially same components as those of FIG. 7 are denoted by the same reference numerals, and detailed descriptions thereof may not be repeated here.

[0088] Referring to FIG. 8, the electronic device 800 may include the distance detection sensor module 810 (e.g., a time-of-flight (TOF) module) disposed under the display 400 in the inner space 7001. The distance detection sensor module 810 may include a light emitting structure 811 (e.g., a vertical cavity surface emitting laser (VCSEL)) for irradiating a laser light, and a light receiving structure 812 (e.g., an infrared camera) disposed near the light emitting structure 811 and detecting light irradiated from the light emitting structure 811 and then reflected by an external object. For example, the light emitting structure 811 and the light receiving structure 812 may be arranged side by side on one FPCB 813, and may be controlled through a control circuit (e.g., a driver IC) (not shown).

[0089] The distance detection sensor module 810 may be disposed, when the display 400 is viewed from above, such that the light emitting structure 811 overlaps the first non-display area 4321, and the light receiving structure 812 overlaps the display area 431. The light emitting structure 811 and the light receiving structure 812 may be disposed to face the display panel 430 through the through-hole 4401 formed in the additional layer 440. In case of the distance detection sensor module 810, a corresponding portion of the display panel 430 overlapping the light receiving structure 812 may have an opening or aperture 4301 perforated for smooth operation of the infrared camera.

[0090] The distance detection sensor module 810 may also be directly attached to the additional layer 440 underlying the display panel 430 through the waterproof member 710. For example, the distance detection sensor module 810 may be disposed to have a third sealing structure (S3) through the waterproof member 710 surrounding both the light emitting structure 811 and the light receiving structure 812 between the FPCB 813 and the additional layer 440.

[0091] When the display 400 is disposed through the lateral member 310 and/or the support member 311, the FPCB 813 of the distance detection sensor module 810 may be attached to the support member 311 through the waterproof member 710 (e.g., a double-sided tape).

[0092] FIG. 9 is a diagram illustrating an example display 400 and an optical sensor module 500 according to various embodiments of the disclosure.

[0093] Referring to FIG. 9, the display panel 430 attached to the rear surface of the front cover 320 includes the display area 431 having the first transmittance, the first non-display region 4321 disposed adjacent to the display area 431 and having the second transmittance greater than the first transmittance, and the second non-display region 4322 adjacent to the first non-display region 4321 and having a transmittance of about 0%. When the display 400 is viewed from above, the optical sensor module 500 is disposed such that the light emitting structure 501 overlaps the first non-display area 4321 and the light receiving structure 502 overlaps the display area 431.

[0094] According to various embodiments, the first non-display area 4321 may occupy only a portion of the non-display area 432 overlapping the light emitting structure 501, and the other portion may be formed as the second non-display area 4322. In this example, because the second non-display area 4322 is expanded relatively, the freedom of layout design for driving circuits (e.g., the driving circuits 4331 in FIG. 6) and wiring structures (e.g., the wiring structures 4332 in FIG. 6) may be increased.

[0095] FIG. 10 is a diagram comparing partial-off portions of a display area 431 depending on an arrangement position of an optical sensor module 500 according to various embodiments of the disclosure.

[0096] Referring to FIG. 10, a processor (e.g., the processor 120 in FIG. 1) of an electronic device (e.g., the electronic device 101 in FIG. 1) may control at least a portion of the display area 431 for smooth operation of the optical sensor module 500. For example, when the optical sensor module 500 is a proximity sensor module, when the electronic device 101 enters a specific mode (e.g., a face recognition mode, a call reception or transmission mode for a video call) for recognizing an object through the light receiving structure 502, and when light emitted from the light emitting structure 501 is reflected on an external object and then returns to the light receiving structure 502, light of a pixel region controlled to the 'on' state in the display area 431 may cause wrong operations of the light receiving structure 502. Therefore, in such a mode, the processor 120 may control the display to partially turn off a certain portion of the display area 431 overlapping the optical sensor module 500 (especially, the light receiving structure).

[0097] In the present invention, where the light emitting structure 501 of the optical sensor module 500 is disposed in the first non-display area 4321, the display area 431 partially turned off has a first width (d1). In a comparative example where both the light emitting structure 501 and the light receiving structure 502 of the optical sensor module 500 are disposed in the display area 431, the display area 431 partially turned off has a second width (d2). Because the first width (d1) is smaller than the second width (d2), this may help in the efficient operation of the display area.

[0098] As described above, the electronic device according to various example embodiments of the disclosure has an improved arrangement structure in which the light emitting structure is disposed at a position overlapping a portion of the non-display area formed to have a relatively high transmittance. Through this, it is possible to prevent and/or reduce a spot phenomenon in the display area caused by the photoelectric effect, and also to prevent and/or reduce performance degradation due to interference by relieving diffused reflection. In addition, by directly placing the optical sensor module on the rear surface of the display, it is possible to contribute to improved assembling efficiency and slimness of the electronic device.

[0099] According to the present invention, an electronic device (e.g., the electronic device 700 in FIG. 7) includes a housing (e.g., the housing 210 in FIG. 2A), a display panel (e.g., the display panel 430 in FIG. 7), and an optical sensor module (e.g., the optical sensor module 500 in FIG. 7). The display panel is disposed in an inner space (e.g., the inner space 7001 in FIG. 7) of the housing and is visible at least in part from an outside through the housing, and includes a display area (e.g., the display area 431 in FIG. 7), a first non-display area (e.g., the first non-display area 4321 in FIG. 7) disposed adjacent to at least a peripheral portion of the display area, and a second non-display area (e.g., the second non-display area 4322 in FIG. 7) disposed adjacent to at least a peripheral portion of the first non-display area.
